McDonnell Douglas Corp.'s LNG-containment system uses an inexpensive support structure to protect the primary nickel-steel membrane against rupture or failure due to thermal and mechanical strains caused by loading and unloading the cryogenic liquid. The system also incorporates a novel corner-support system to react against the tension and bending of the primary liner caused by thermal stresses. The primary membrane is connected to the adjacent foam insulation by a tongue arrangement, the tongue's being received and held in place by retainers positioned within the insulation. At 90/sup 0/ corners, a system of insulating rods and couplers reacts against plywood corner supports for transmitting tension loads from the primary membrane to the outer wall or hull of the tank or ship.
